when a hockey puck hits a stick,glass etc. there is a sound(and a distinct sound),also a baseball hits a bat there is a sound(a distinct sound) there too,what then is causing the sound, if not physical contact(solid contact). if there is an regression to infinity of no actual contact of things,what then is the essence of sound?

for is not the essence of sound, solid contact? at least here?

I have been watching this one from the sidelines. But I think the issue is somewhat symantical.

Question. When you rap your finger on the desk with impatience, do you think the thump you feel and noise you hear is "Solid" contact?

It actually depends on your definition of what matter is. The electrons in your finger repell the electrons in the desk by the charge field.

The electrons do not collide with the other electrons. They don't even get close. Atoms are substantially spatial voids. But then if you consider the fields around atoms as part of matter then all matter in the universe is in constant contact.

How can something in contact then collide?

You can't have it both ways.

i think i understand your point now. are you saying that because all matter is in constant contact that the infinity of scale would absorb all ability to produce sound? and therefore produce none?(sound)

it would be interesting to find out if accelerator collisions produce sound!!

Not quite what I meant. I don't personally accept infinity at any level of physical reality. The making of sound is really not contengent on being or not being in contact. It is the ability to create precussion waves in a carrier medium. - i.e. air, water, etc.

EM waves can ultimately be classed as sound of sorts and indeed can be received and converted to actual sound that we hear. The loudness of that sound depends on the strength (energy) of the wave. The sound being audiable or not depends on the frequency of the wave.

But these are know simple attributes of sound. I don't see your correlation. Sound and Solid have no connection. Being in contact by EM or gravity or considered seperated as points of matter, neither alter the process of producing sound.

Collision is not the origin of sound, formation of precussion waves is sound. A rapid increase of EM stength (finger electrons EM pushing against the desk electron EM) makes sound by affecting electron in the surounding air and producing precussion waves.

The finger, the desk and the air are all merely coupled by EM fields of the electrons of their respective atoms.

i don't think that the above statement is entirely true,for where do the percussion waves come from? drums, a percussion musical instrument,needs the drum stick to hit the skin of the drum to produce sound, your not suggesting that the percussion waves came before the contact of the stick with the skin are you?

define collision.if any.

just want to clear here.
